⚙️ TECHNICAL SPECIFICATIONS
Technical Detail
Measurement / Info
Component Product Profile
Common Rail Fuel Injector Nozzle Base Sealing Washer
Material Composition Matrix
Pure Solid Soft-Annealed Sealing Copper (Optimized for exact micro-crush behavior under engine hold-down clamp torque specifications)
Thermal & Pressure Barrier
Acts as a critical frontline shield at the combustion chamber interface, deflecting extreme firing temperatures away from the delicate injector tip while containing extreme compression loads.
Operational Focus
Completely prevents catastrophic combustion gas blow-by into the upper valve rocker cover area. Prevents severe carbon/soot accumulation around the injector bore, stopping the injector from binding or sticking.
Maintenance Directive
Strictly single-use component. Must be discarded and replaced every single time a common rail fuel injector is pulled out for testing, replacement, tip service, or core diagnostic changes.
Quality Seal
ELRING – Das Original (Certified Premium Commercial Diesel Common Rail Isolation)
